ATTORNEYS TAMBOURINE This invention relates to improvements in a tambourine.

It is an object of the present invention to provide an im proved tambourine which is simple in construction and adapted for mass production.

Another object of the invention is to provide an improved tambourine which has a nice appearance and convenient to handle.

Still another object of the invention is to provide an im proved tambourine in which the securement of a sheet is simple and the sheet thus secured will not be permitted to loosen and always generate beautiful sounds.

A further object of the invention is to provide an improved tambourine which is so constructed that bells or other soundgenerating elements can be secured to the outer periphery of the body of the tambourine in a simple manner.

In order to attain the objects set forth above, the tambourine according to the instant invention comprises a pair of front and back frames made of a synthetic resin and adapted to be mated with each other in interlocking relation, said front and back frames consisting of annular pieces provided with interlocking projections and recesses on the mating surfaces and with annular grooved steps on the outer peripheral surfaces thereof and having halves of a handle integrally formed at portions of the outer peripheral edges thereof respectively, a sheet adapted to be clamped between said annular pieces at its peripheral edge portion and having through-holes perforated therein for engagement with the projections on one of said annular pieces, a strip or ribbon adapted to be fitted on said annular grooved steps formed on the outer peripheral surfaces of the annular pieces of said pair of frames with the opposite ends thereof secured to said handle and a plurality of bells or other sound-generating elements secured to said strip or ribbon at a predetermined interval.

According to the invention, as stated above, a pair of the front and back frames are provided with the interlocking projections and recesses on the mating surfaces thereof, and the sheet is provided with the through-holes in the outer peripheral edge portion thereof for engagement with said projections. Therefore, when the sheet is clamped between the annular pieces at its peripheral edge portion, it is tightly secured between the frames, and a relative displacement of the frames and a relative displacement of the sheet and said frames can be prevented and the sheet is always held taut within said frames without being permitted to loosen, so that the sounds generated by the tambourine will not vary during use.

Furthermore, according to the invention the annular grooved step are formed on the outer peripheral surfaces of the annular pieces of the frames, and the strip or ribbon having the bells or other sound-generating elements secured thereto at the predetermined interval is fitted in the groove defined by said annular grooved steps, with the opposite ends thereof secured to the handle. Therefore, the bells or other sound-generating elements can be secured to the body of the tambourine in a simple manner.

Still further, the tambourine according to the invention can be produced simply by assembling a pair of the front and back frames, the sheet and the strip or ribbon having the bells or other sound-generating element secured thereto, with each other, and hence is adapted for mass production.

Still further, according to the invention the frames are made of a synthetic resin and, therefore, the tambourine of the invention is beautiful and highly durable.

Other objects, features and advantages of the present invention will become apparent from the following description on an embodiment of the invention.

In the drawings,

FIG. 1 is a front elevational view showing a preferred emboriment of the tambourine according to the invention, with a portion thereof broken away;

FIG. 2 is a side elevational view of the embodiment of FIG. 1;

FIGS. 3 and 4 are cross-sectional views taken on the lines Ill-Ill and Iv-IV of FIG. l respectively; and

FIG. 5 is a perspective view of the sheet.

In FIGS. 1 through 4, reference characters A, B designate a front and back frames respectively which are made of a synthetic resin, C a sheet stretched between said frames, and D a strip or ribbon of synthetic resin having a plurality of bells E secured thereto at a predetermined interval.

An annular piece la which constitutes the body of the front frame A is provided with recesses 2a at a predetermined interval in the inner surface, a handle portion 3a at a portion of the outer periphery and an annular projection 4a along the outer edge thereof, said annular projection 4a having an L-shaped cross-section with an inwardly open annular grooves formed therein.

An annular piece lb which constitutes the body of the back frame B is provided with projections 2b on the inner surface which are to be engaged in the recesses 2a respectively, a handle portion 3b at a portion of the outer periphery and an annular projection 4b along the outer peripheral edge thereof, said annular projection 4b having a L-shaped cross-section with an inwardly open annular groove formed therein. The annular piece lb is further provided along the inner edge of the inner surface thereof with an annular projection 5 for engagement with the inner peripheral surface of the annular piece la.

The sheet C, as shown in FIG. 5, is formed with throughholes 6 at the outer peripheral edge portion thereof, for engagement with the projections 2b.

The strip or ribbon D is made of a flexible synthetic resin and has the bells E secured thereto at a predetermined interval through fittings 7. The opposite ends of the strip or ribbon D are received in recesses 8 formed in the opposite side faces of a handle composed by the handle portions 3a, 3b and secured thereto by means of washers 9 and tightening screws 10 respectively.

In assembling the tambourine of the construction described above, the projections 2b on the annular piece 2a of the back frame B are extended through the through-holes 6 in the sheet C respectively and then the tip ends of said projections 2b are engaged in the respective recessed 2a formed in the annular piece In of the front frame A. At the same time, the annular pieces la, 2a and the handle portions 3a, 3b of the front and back frames A, B are mated and adhesively bonded with each other. Thus, the sheet C is stretched taut between the front and back frame A, B, and the main body and the handle of the tambourine are composed.

In this case, the annular projection 5 on the annular piece lb of the back frame B is fitted over the inner peripheral surface of the annular piece 1a of the front frame A to radially stretch the sheet C, so that said sheet C is uniformly tightly stretched between the annular pieces 1a, lb of the front and back frames A, B in all directions toward the periphery of said annular pieces.

Upon assembling the annular pieces 1a, lb of the front and back frames A, B in the manner described to form the frame and handle of the tambourine, an annular groove is formed along the outer peripheral surface of the frame by the L- shaped annular projections 41, 4b of said frames A, B. The strip or ribbon D is fitted in the annular groove thus formed, and the opposite ends of said strip or ribbon D are placed in the recesses 8 formed in the opposite side faces of the handle and secured to said handle by the washer 9 and the tightening screws 10. By this step, the assembly of the tambourine is completed.

It will be understood that the interlocking recesses may be provided in the annular piece lb of the back frame B and the interlocking projections on the annular piece la of the front frame A.

It will also be understood that the handle may be provided separately from the front and back frames A, B and secured to the outer peripheral surfaces of the annular pieces la, 1b of 5 the frames A, B.

Although the present invention has been described and illustrated herein in terms of an embodiment thereof, it should be understood that the invention is not restricted to the embodiment but many changes and modifications are possible without departing from the spirit of the invention.
